Engine Mechanical problem
2002 Toyota Corolla 4 cyl Front Wheel Drive Manual 137000 miles
----------------------------------------------------------------
Hello. I have a 2002 Toyota Corolla milage 137000. I had the car for almost three years until about a few weeks ago the check engine light came on. The car was working normally at the beginning but I noticed whenever I filled up for gas the car would have a hard time starting up and it would almost stall.

I went to a friend who has a diagnostic machine and he connected it to my engine and it came up with two error codes:

PO 441: Evaporative emission control system incorrect

PO 446: Evaporative emission control system vent control circuit malfunction.

What do you guys think what is going on with my car so that I could tell the mechanic exactly what the problem is and if possible, could you give me an estimation of how much the repairs are going to cost.

check the gas cap and make sure its on tight and that you may need a new one and check the evap canister solenoid, its probably faulty , check these items in this order.
